1. Choice of secondary protector and feed resistor should ensure these ratings are not exceeded. A minimum 400
feed resistor is recom-
mended.
2. This parameter is not tested in production. It is guaranteed by design and device characterization.
3. Applied voltage is 100 Vp-p square wave at 100 Hz to measure dV/dT sensitivity.
